Application led .Tune 21, 1910. Serial No. 568,574.

To all 'whom it may concern:

Be it known that I, JOHN B. ALLBEE, a citizen of the United States ofAmerica, and resident of Rolfe, Pocahontas county, Iowa, have invented anew and useful Covering Attachment for Planters and Disks, of which thefollowing is a specification.

The object of this invention is to provide improved means for coveringthe wheel tracks of corn planters and also for covering the spacebetween sections of a disk harrow.

My invention consists in the construction, arrangement and combinationof elements hereinafter set forth, pointed out in my claims andillustrated by the accompanying drawing, in which- Figure 1 is a plan ofthe truck frame of a corn planter showing my improved device appliedthereto as required for practical use. Fig. 2 is an elevation of thesame. Fig. 3 is a plan of a disk harrow showing my improvement appliedthereto. Fig. 4 is an elevation, partly in section, on the indicatedline 4-4 of Fig. 1. Fig. 5 is a plan illustrating a modifiedconstruction of some of the parts. Fig. 6 is a rear elevationillustrating a modified construction of scraper blade employed in thedevice. Fig. 7 is a rear elevation illustrating` a further modified formof scraper blade employed in the device. Fig. S is a plan illustrating afurther modified construction of some of the elements employed in thedevice. Fig. 9 is a cross-section on the indicated line 9--9 of Fig. 8.

In the construction of the device as shown in Figs. 1, 2 and 4 thenumeral 10 designates a rod mounted transversely of and extending at itsends beyond the frame 11 of a planter. The frame 11 is carried by anaxle 12 and the axle is supported in and by wheels 13, 14. Clevises 16,17 are mounted on and depend from end portions of the rod 10. Wheelscrapers 15 of common form are mounted on end portions of the rod 10within the clevises 16, 17 and are adapted to depend from the rod andscrape the wheels 13, 14. Hooks 18, 19 are mounted on and depend fromthe clevises 16, 17. Tongues 20, 21 are pivoted at their forward ends toand adapted to be drawn by the hooks 18, 19, and said tongues are bentdownward at their rear ends to form ears 22, 23. Angle plates 24 aremounted beneath the rear end portions of the tongues 20, 21 and one armof each angle plate is apertured in registration with an aperture 1n anear 22 or 23. The angle plates are further connected to the tongues bybolts 26, 27 and washers 28 may be mounted on the bolts 27 to spaceapart the forward ends of the angle plates from the tongues. l

Scraper blades 29, 30 are mounted at their centers on the short arms ofthe angle plates 24 and are secured thereto rigidly as by rivets 25.Apertures are formed in the centers of the scraper blades 29, 30registering with the apertures in the short arms of the angle plates andin the ears 22, 23 and bolts 31, 32 are mounted through -saidregistering apertures and connect the scraper blades, angle plates andears. The central portions of the scraper blades 29, 30 are straight andextend transversely of the angle plates and tongues, and end portions ofsaid blades exj tend forwardly in diverging planes and are beveled orswaged out to edges on their lower margins. Thus the sw'aged marginsproject below the central straight portion and draw loose soil to acentral path passed over freely by said central portion. The use ofwashers 2S provides for adjusting the scraper blades so as to determinethe cut, pitch or inclination thereof relative to the surface of theground on which they are used. A rod 33 is pivoted at its ends to andconnects the tongues 20, 21. A lever 34 is fulcrumed on the frame 11 andis connected at one end to the'c'entral portion of the rod 33. A lever35 is fulcrumed on the axle 12 and is connected at one end to the lever34 and is formed with a pedal 36 on its opposite end. The lever 35 maybe attached to the usual hand lever employed to raise and lower theplanting mechanism so as to be operated conjunctively therewith. Vhenthis device is attached to a disk harrow' as shown in Fig. 3 the tongue20 is attached to and trails from the frame 37 between adjacent disks38, 39 in such manner that the scraper blade 29 bridges the spacebetween and crosses the paths of travel of said disks. A weighted box 40is mounted on each tongue 20, 21 and is adapted to receive weightingsubstance, such as4 sand orv rock, to the amount required to hold thescraper blades 29, 30 in proper engtgement with the soil on which theyare use In practical use of the device on a corn planter the scraperblades trail behind the wheels 13, 14 and scrape or drag soil fromeither side of the wheel tracks into said tracks, the central portionsof said blades passing over the wheel tracks and covering soil withoutdisturbing the planted seed corn. Inasmuch as in ordinary use theplanter wheels sink approximately one inch into the ground it isdesirable that the scraper blades should cut approximately the' samedistance into the ground and dra-w a sufiicient quantity of soil to fillthe tracks. Then it is desired to change the d'irection of travel o-fthe planter the lever 35 is operated to actu-ate the lever 34 and raisethe rod 33, tongues and scraper blades. The flexiblev connectionsbetween the several parts permit the machine to be turnedl withoutraising the tongues and scraper blade if necessary, but it is better toraise them and thus avoid unnecessary scraping of the soil surface. Inthe use of the device on a disk barrow as shown in Fig. 3f a singletongue, angle plate and weight box are employed and the scraper bladeextends across the space between sections of the disk harrow and scrapesand drags loosened soil upon such space.

In the construction of the device as shown in Fig. 5 the scraper isformed of Asepa-rate members rigidly connected as follows: A centralmember or bar 29al is secured to the angle plate 24 in like manner asthe central portion of the blade 29 is secured. End portions of the bar29a are inclined forwardly and scrapers 29", 29c are arranged at obliqueplanes on said end portions and secured thereto by bolts or rivets 29d.The blades 29b and 29c are wider than the bar 29a and project below saidbar by means of beveled edges. The operation of the scraper constructedaccording to Fig. 5 is the same as that constructed according to Fig. 1.

In the construction of the scraper' 30 as shown in Fig. 6 the divergingend portions 30a, 30b thereof are formed with scalloped lower margins30C, 30d and this construction has been found towork more satisfactorilyin some kinds of soils than the construction having plane lower margins.

In the construction of the device as shown in Fig. 7 the scraper blade29 is formed with a straight central portion adapted to be attached toan angle plate 24 and ton-gue and also is formed with diverging arms 29having outstanding rearwardly projecting flanges 40, 41 on their lowermargins. Harrow teeth 42 are mounted through vertical holes in theiianges- 40, 41 and are secured thereto by nuts 43, 44 above and belowthe flanges. 'When the device is constructed according to Fig. 7 thereis a tendency on the part of the teeth 42 to break up and pulverizeclods engaged thereby preliminary to scraping the substance thereof intothe wheel tracks or into the spaces between sections of a disk harrow.

In the construction of the device as shown in Figs. 8 and 9 the tongue2Oa is formed with a tapering sleeve 20b at right angles to its rear endportion, which sleeve is fitted to a tapering socket 20 carried by aplate 22a. The' plate 22a is adapted to be riveted to the scraper blade29'. A bolt 45 is mounted through the tapering sleeve 2Gb and throughthe smaller end portion of' the tapering socket 2OG and is held by a nut46. This construction eliminates the angle plate 24, bolts 26, 27 andwashers 28 and permits of an adjustment of the scraper blade 29 relativeto the tongue by adjusting the socket 20c ro` tatively of the sleeve 20.Rigid connection between the socket and sleeve is effected by the bolt45 and nut 46 and may be made very effective because of the taperingconstruction of the contacting faces ofsaid sleeve and socket.

I claim as my invention- 1. In a scraping' attachment, a tongue, anangle platel mounted beneath and longitudinally of said tongue andadapted for vertical adjustment relative' thereto, a scraper blade fixedto one arm and extending transversely of' said angle plate, means forconnecting the scraper blade, angle plate and tongue, and means forattaching said tongue to an implement.
